Cities ranked by the records

Showing 1 of 1 cities · scores are system-level, not tap tests

Ranked by the Purity Score of each city's main water system, highest first. Scores belong to water systems; there is no county score. The score is computed only from contaminants measured in the published EPA record, so this ranks the record, not which city's water is safest. How the score works.

Frequently asked

How does Vigo County tap water compare across cities?

PurityMap ranks 1 city in Vigo County by the Purity Score of each city's main water system, computed only from contaminants measured in the published EPA record. Scores belong to water systems, not to cities.

The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.

How many Vigo County cities have PFAS above the federal limit?

1 city of 1 had at least one regulated PFAS (PFOA, PFOS or PFHxS) measured above the 2024 federal limit in EPA's UCMR 5 testing, including Terre Haute (PFOS 5.2 ng/L). PFAS were detected at any level in 1.

Is there lead in Vigo County tap water?
